1 b all wild/2t it concern.

Be it known that I, llnaM-A N Dnrrnn MANN, a subject of the Emperor of Germany, residing 1n Nowawes-Neuendorf, Ger many, have lnvented certain new and useful Improvements in Methods or: Covering 'lhread-Buttons, of" which the following is L specification. I l

This invention relates to a method for covering buttonsand particularly for covering buttons with thread.

The main objects of the invention are to contrive a method for covering buttons which can be entirely performed by machine; in which there are but three principal steps; by which a particularly artistic button is quickly produced; by which a durable covering is produced, by which those parts of a button covering which are subjected to the most wear are in the natural course of the method covered with the most thread; and which can be performed at low cost of manufacture. I

These and other features, capabilities and advantages of the invention will appear in the subjoined detailed description of one specific embodiment thereof, the product of which is illustrated in the accompanying drawings in which- Figures 1, 2 and 3 are plan views of the button in actual size, Fig. 1 illustrating the button after it has been subjected to the first principal step; Fig. 2 illustrating the button after it has been subjected .to the second principal step; and Fig. 3 illustrating the completed button after it has been subjected to all three principal steps and is ready for the market.

Figs. 4, 5 and 6 are enlarged plan views of the button corresponding to Figs. 1, 2 and 3 respectively.

Fig. 7 illustrates a fragmental enlarged plan view showing a portion of the intermediate weft.

This application is a divisonal application of my patent application Serial No. 767,464, filed May 13, 1913.

As illustrated in Fi s. 1 and 4:, a foundation ring 1 composed of metal or other suitable material is covered with the thread 2 which is wound transversely of the annular portion of the ring member, that is, wound around said annular portion whereby a securing surface is formed on said ring for thread winding of the next step.

was; Serial nti 18,179.

. W'lieii the annular portion has been com pletely" covered in this manner, the. result ing thread-covered ring is ready for theneiat step. i

1 Preferably the same thread 2 may be used for the second principal, step, without cutting off such thread after-having finished the first step. The second principalstep conslsts 1n winding the thread, as 2 around the covered ring-diametrically ofsaid ring, that is, diametrically of the disk outline "formed; by saidring into a star-lilte warpso that-tl'ie threads which constitute such warp will cross each other at the center of the ring as illustrated in Figs. 2 and 5. By this covering, it will be seen that, not only is the button produced, butthe ring or edge of the button, which will be subjected to the greater wear, receives two coverings of thread. The foregoing main steps are preferably performed by'machine and can be conveniently performed by the machine disclosed in my patent application Serial No. 767,4L64t, filed May 13, 1913, of which this application is a divisional application.

The next and last principal step is preferably performed on a tambour machine. In this last step the button, after having been covered by two layers of thread in the first two steps, is provided with an intermediate weft in which a thread 3 is inter" woven between the diametrically extending portions of the thread 2 to secure the same in position, the thread being illustrated, (Figs. 3 and 6) in the present instance, as forming a complete circle which is the line that is a circle concentric with the ring 1 and intermediate the center of said ring and the periphery of said ring. By this last weft, the crossing threads of the star-like warp produced by the second principal step are firmly secured in position.

This intermediate weft formed by the thread 3 is clearly illustrated in Fig. 7, in which the thread 3 is shown (going from right to left) as forming a knot having a portion a passing under one of the diametrically extending portions of the thread 2', then forming a loop I), from which its portion 0 again passes under said diametrically extending portion of the thread 2', then turns so that its portion (2 passes over such diametrically extending portion, whereupon .it passes through the loop 6 after Q Which it passes on to form a similar knot on the next diametrically extending portion of the thread 2.

Forming this knot howeverthe portion 0 returns not only under the diametrically extending portion, but also through the fore: going loop 6. All the following knots are formed similarly as the second one, until the intermediate weft is finished.

The method consists essentially of three principal steps but obviously these can be departed from in certain respects as for instance by omission and addition, without departing from the general scope of the invention, as defined by the appended claims- I claim:

1. The method of manufacturing thread buttons which consists in taking a foundation ring, winding thread around the annular portion of said ring whereby a securing surface is formed for the thread winding of Copies of this patent may be obtained for thread buttons which consists first, in taking a foundation ring, winding thread around the annular portion of said ring whereby a securing surface is formed for the thread winding of the next step, then Winding thread diametrically of the circular disk outline formed by said ring'whereby the peripheral edge of said ring receives two covers, and then interweaving thread between the threads of the diametrical warp to secure the same in position and to one another.
